A cumulative frequency distribution lists the number of observations that are within or below each of the classes.

- Which of the following best describes a frequency distribution A frequency distribution is a grouping of:（） A: data into intervals (classes) so that the number of observations in each of the non - overlapping intervals (classes) can be seen and tallied. B: selected data into intervals (classes) so that the number of observations in each of the non - overlapping intervals (classes) can be seen and tallied. C: dependent intervals (classes) so that they can be seen and tallied.
- Individual observations within each class may be found in a frequency distribution.
- A relative frequency distribution describes the proportion of data values that fall within each category.
- If the values of the seventh and eighth class in a cumulative percentage distribution are the same, we know that there are no observations in the eighth class.
- True or False: If the values of the seventh and eighth class in a cumulative percentage distribution are the same, we know that there are no observations in the eighth class.
